My point is that it seems a stretch to suggest that a player who has not lead his team anywhere or accomplished anything of significance
He "led" the Grizzlies to three straight 45-50 win seasons and playoff appearances. He has played at an all-star level for four straight years. (Having five total years.) He is one of the twenty best players in the league. I would say that is a pretty solid record.
but all the same time Gasol hasn't established himself as a player who guarantees playoff success. I don't think it's illogical to be skeptical of a player, who is for the most part unproven in the postseason, and his ability to vault the Bulls into immediate contention.
Blaming a teams' best player for the teams' faults is highly illogical and yet it keeps being perpetuated. (see McGrady, Garnett, etc. even though nobody seems to blame Jordan for the Bulls' failures back in the day

)
Gasol's playoff performance was on par with his regular season performances, but not only did they face vastly superior teams all three times, a few of his teammates have always crapped out in the playoffs.
I think it is entirely stupid for the Bulls to not get a player because he's "unproven in the postseason" because his team has not won anything. (And that logic could preclude them for trading for Garnett and O'Neal who have not won anything past the second round.) Every single one of these Bulls is pretty much as "unproven" exempting Wallace (who is a one-way player now) and P.J. Brown (who is terrible) so I think it is a mute point. Ignoring "provenness" no one on this team has anything on Gasol's total package. He is a top twenty player, who is deadly on offense, and would have boosted a starved unoffensive team.
This current team "competes" because the East is a wasteland, Pau would have improved the offense a ton and the Bulls would have been legitimate contenders. I do not see how you can ignore what Pau would actually do on the court just because his teams were beat around by the cream of the crop in the West.
Take a look at the Bulls C/PF rotators: (ORtg is points produced per possession...times 100 to look pretty)
Wallace: 85.3 ORtg (8.9 poss per game, 10.4 poss per 40)
Brown: 80.2 ORtg (7.8, 16.3)
Allen: 82.0 ORtg (5.0, 19.0)
Sweetney: 83.8 ORtg (4.9, 22.0)
Khryapa: 80.0 ORtg (3.8, 18.5)
Thomas: 80.1 ORtg (5.3, 19.3)
Nocioni: 102.0 ORtg (15.3, 22.0)
First Seven: 82.4 ORtg
All Eight: 88.3 ORtg (Which is counting all of Nocioni's minutes as being at PF or C which they clearly aren't.)
Then there's Gasol: 104.9 ORtg (21.9, 24.4)
Replacing just half of those first seven players possessions with Gasol improves the Bulls offense over five points (since everyone loves points per game...the Bulls currently score 99ppg with Gasol taking just half the above possessions they would score over 104ppg) and the removal of Deng does neglible damage as his possessions would be split between the super efficient Bulls backcourt and Gasol.
Gasol is an average defender, and better than Allen and Sweetney who are terrible, AND the Bulls defense is powered by its' backcourt not its' frontcourt, so the Bulls defense wouldn't be hurt too badly (almost not at all actually, as Gasol's shot blocking makes up for the slight position advantage the aging Brown brings anymore) even knocking them two points on defense (which is more than they would drop, but I'm playing it safe) they would still be better.
From 99ppg for, 94.5ppg against. To 104.5ppg for, 96.5ppg against. From +4.5 to +8.0. And this is all ignoring that the Bulls backcourt players would become MORE EFFICIENT because instead of zero inside scoring to guard (nobody has to guard Wallace-Brown/Allen, so the Bulls play 3-on-5) teams would have to pay attention to Gasol, opening up the outside more. (As a side note, the Bulls should be a 54 win team with their current point differential, but they are only on pace to be a 46 win team...on the same adjustment they would be on pace for 52 wins and have a pythag of 62 wins.)
The key to this deal is not that you are just adding Gasol, but that you are taking possessions away from the horrible Bulls frontcourt and giving them to a super efficient frontcourt scorer. Is Gasol in the same class as Wade, Dirk, Ming, Duncan and Kobe? (And then you have KG, LeBron who float in and out of that top five...) No, but he is easily in that next tier of players.
(And while I am in my fantasy land, if the Bulls also could've gotten Atkins in the deal...rawr...they probably would've leaped into the top ten on offense.)
The playoffs are better suited to the Bulls style of play at the moment. Good defensive teams will usually fare better in the post-season
The last below average offense to win a title? 1994 Rockets, and they had Hakeem. Before that was the 1979 Sonics. Betting on a terrible offense and great (but not the runaway best) defense isn't the smartest idea.
Title teams are great on BOTH ends. (Even the suprise Heat of last year were top ten on both offense and defense.) The Bulls are only great on one end. In the East the Pistons are 5th on offense, 6th on defense. The only top ten (nearly top five!) in both team in the East, which tells you why the Bulls still have a shot at coming out of the East...even without a frontcourt that can score.
I guess I am different and just like to build teams that have huge advantages over their competition instead of just being "good enough" to take advantage of a situtation.
